Danger Detection

Since an Absolute Immortal is Immortal and can't die or have to worry about all forms of Injury, How would them having a danger sense work?

Melancholy.

The user is able to visually perceive emotions as a multitude of colours; the deeper the colour, the more intense the emotion is. These colours can appear anywhere - from individuals to buildings - and usually appear 5-10 minutes before the event causing these emotions occurs. The events that would cause these emotions could then be circumvented if the user wishes to do so.

Primary colours represent a simple emotion, like rage and sadness. Secondary colours illustrate a more complex emotion, like fear and disgust. Tertiary colours demonstrate an extremely complex emotion, like schadenfreude. Monochromatic colours constitute an intense depression or devotion. If an individual is coloured in a deep crimson, they are feeling an immense rage, while if an individual is coloured in a weak red, they're just feeling a slight annoyance.

The applications of this power are that it can be used to foretell future events; the incident occuring in a dark alleyway coloured in a deep crimson would almost undoubtedly be a murder, whilst the incident occuring in front of a gravestone coloured in a deep blue would be an individual mourning the death of a loved one. Some offensive uses of this ability are that it can be used to accurately pinpoint the weakpoints of opponents; as a weakpoint would be coloured in a moderate red (symbolising the opponents' rage if you were to hit them). It can also be used to predict and evade danger, as if another superpowered individual with earth manipulation (it's hypothetical) had been intending to cause a landslide under you, the area around you would be coloured in a deep red.

To be honest, I made this ability broader by including all emotions, rather than just intense sadness and depression - which is melancholy. Still, I think that this relates to melancholy due to the capability of detecting intense emotions.
